Abstract
Techniques are disclosed for obtaining data using memory timing characteristics. In some embodiments, a physical unclonable function is used to obtain the data. In various embodiments, a computer system programs a timing parameter of a memory accessible by the computer system to a value that is outside of a specified operable range for the timing parameter. In various embodiments, the computer system performs one or more memory operations to a least a portion of the memory and detects a pattern of errors in the portion of the memory. In some embodiments, the computer system generates a response dependent on the pattern of errors. The response may be used to identify the computer system.
